This paper proposes gradient routing with two-hop information for industrial wireless sensor networks to enhance real-time performance with energy efficiency. Two-hop information routing is adopted from the two-hop velocity-based routing, and the proposed routing algorithm is based on the number of hops to the sink instead of distance. Additionally, an acknowledgment control scheme reduces energy...
This paper studies gradient routing with two-hop information for industrial wireless sensor network to enhance real-time performance with energy efficiency. The two-hop information routing is adopted as that in two-hop velocity based routing and the proposed routing algorithm is based on the number of hops to sink instead of distance. Furthermore, an acknowledgement control scheme reduces energy consumption...
One of the most important and challenging issues in real-time applications of resource-constrained wireless sensor networks (WSNs) is providing end-to-end delay requirement. To address such an issue a few QoS routing protocols have been proposed. THVR (Two-Hop based Velocity based routing protocol) is newly proposed real-time protocol is based on the concept of using two-hop neighbor information for...
Enabling real time applications in Wireless Sensor Networks (WSNs) demands certain delay and bandwidth requirements which pose more challenges in the design of networking protocols. Therefore, enabling such applications in this type of networks requires energy and Quality of Service (QoS) awareness in different layers of the protocol stack. In many of these applications (such as multimedia applications,...
Wireless sensor network (WSN) have recently been extensively deployed and researched. They are composed of a high number of small and simple nodes where most of them have to function as a router in an ad hoc manner. Because of limited energy sources in sensor network node, routing protocols should save the energy as much as possible. Energy consumption has a direct influence on network lifetime. From...
In wireless sensor network (WSN), sensor node is limited in energy, thus energy efficiency is an important concern in routing protocol design. And some applications in sensor networks have the requirement of timely delivery, real-time also become needed for routing. Directed diffusion (DD) is a data centric dissemination protocol for sensor networks, but DD cannot support time-sensitive traffic nor...
In Wireless Sensor networks (WSNs), most existing routing protocols do not consider a node mobility problem, because nodes in sensor network are generally assumed to be static.The network may get partitioned, due to the mobility of some nodes will cause other nodes to lose their connection with the network. Network partitioning poses significant challenges to the provisioning of continuous data streaming...
As the growth of multimedia communications involving digital audio and video, it is increasingly important for the MANET (mobile ad hoc network) routing protocols to simultaneously support both real-time and non-real-time traffic. MANET energy management should offer this support because devices are equipped with limited battery power. To achieve this end, we revise the ad hoc on-demand distance vector...
